This Medicinal Herb Use Did Not Lower Testosterone Levels: 2026 Study
A newly published 2026 study from the University of Geneva (UNIGE) found that medicinal herb use in young men was not associated with lower testosterone levels.
Researchers analyzed blood plasma from 94 healthy men aged 18–23 using advanced LC-MS/MS steroid profiling.
Key findings:
Medicinal herb users showed approximately 23% higher testosterone levels compared with non-users.
Higher levels of androstenedione and dihydrotestosterone (DHT) were also observed.
Researchers found no clear evidence that the medicinal herb improved s***m quality.
The study suggests the relationship between the medicinal herb, hormones, and fertility is more complex than previously believed.
The researchers also noted that previous studies on the medicinal herb and testosterone have produced inconsistent results, with some reporting suppression, others finding no effect, and newer human studies increasingly reporting normal or slightly elevated testosterone levels among users.
Importantly, the study does not conclude that the medicinal herb improves fertility or overall reproductive health. Long-term effects and the impacts of heavy use still require further investigation.
